To all whom it may concern.-

Be it known that I, GEORGE T. STOCKTON, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Insole Cutters and Pasters, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention has relation to improvements in insole cutters and pastors;and it consists in the novel details of construction more fully setforth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the machine; Fig. 2 isa top plan on a somewhat larger scale; Fig. 3 is a verticalcross-section on the line 33 of Fig. 2 taken through the bed-plate; Fig.4 is an end elevation (broken in the middle) Fig. 5 is a cross-sectionof an insole; Fig. 6 is a crosssection of an insole with the layer ofduck in proper position to be applied thereto; and Fig. 7 is a similarsection with the ducklayer creased over the insole channel-lip or flangeto which the welt is secured.

The present invention finds application at that stage in the manufactureof shoe insoles, where the reinforcing layer of duck (canvas orequivalent material) through which are passed the stitches which securethe welt, is pasted to the insole proper.

The object of the invention is to provide means for facilitating thepasting of the duck layer to the sole, and at the same time prevent itsadhesion to the channel-lip or flange formed on the insole over whichthe duck is folded and clenched (or beaten) by the insole machinepreparatory to sewing on the welt.

A further object is to so paste the duck to the insole withoutdisturbing the channellip, which must always be raised above the face ofthe insole, or assume as nearly as possible a direction at right anglesto the in-' sole face, in order that the insole machine may successfullyfold and crease the duck over the channel-lip, preparatory to sewing onthe welt.

The advantages of the invention will be fully apparent from a detaileddescription thereof which is as follows Referring to the drawings, 1represents a standard for supporting one end of the bedplate 2 of themachine, the opposite end of the bed-plate being secured by means ofscrews 3, 3, passed through the lugs 4L, 4:, to a platform 5 over whichis rotatably mounted a roll of duck D constituting the bottomreinforcing layer for the insole E, the said layer being first pastedalong the bottom face of the insole for a distance correspond ing to thelength of the channel-lip or flange 6 formed 011 the insole, and thencreased and beaten around the channel-lip (Fig.7) bythe insole machine(not shown) thereby properly reinforcing the channel-lip to receive thestitching by which the welt is secured to the channellip. These featuresare of course, well known and are merely alluded to so that a clearerunderstanding may be had of the invention proper.

Cast with the bed-plate 2 at the discharge end of the machine is aterminally forked member or arm 6, the bottom fork members receiving thepivotal pin 7 of an oscillating lever 8 to the outer end of whose longarm is pivotally coupled the upper end of a link 9, the lower endthereof being pivotally secured to a pedal-lever 1O hinged to the floora. The end of the short arm of the lever 8 is loosely coupled to avertically reciprocating bar 11 operating freely through a bracket arm 2cast with the bed-plate, the upper end of said bar being connected to anoscillating blade-carrier lever 12, in a manner to allow for theoscillation of the blade with a reciprocation of the bar. The connectionis by means of a pin 13 traversing a slot 8 in the rear arm of the lever12,

the bar being forked to receive said arm. It may me stated in passingthat the lower end of the bar 11 is likewise forked to receive the shortarm of the lever 8, a pin 14 traversing the slot 8 formed in saidlever-arm. The free end of the rear-arm of the lever 12 is coupled toone end of a retracting spring 15, the opposite end of the spring beingsecured to a depending bracket 16 bolted to the arm 2, at the base ofthe forked guide-member 17 by which the blade-arm is guided in itsoscillations. Cooperating with the blade 18 of the lever 12 is astationary complementary blade 18 bolted to the end of the bedplate 2.

It will be seen from the foregoing that a depression of the pedal-lever10 will result in an upward oscillation of the rear arm of theblade-lever 12, and a consequent depression of the blade 18 to cooperatewith the blade 18, the spring 15 returning the parts to their originalposition upon release of the pedal 10. These features however, are allwithin the skill of the mechanic and are not claimed herein, except asthey may enter as elements of the combinations forming thesubject-matter of the present invention.

Mounted to the bed-plate 2 and substantially in the path of the centralline of the sheet unwound from the roll D, are blocks 19 which form aridge or hump from which the sides of the sheet D will necessarily droopmore or less as the sheet is passing over the blocks. This dlOOPingaprevents the duck sheet from engaging the often sensitive and pliablechannel-lip e of the insole E laid on the gummed face of the sheet toeffect adhesion thereto, thus leaving the channel-lip undisturbed (Fig.6) to be delivered to the insole machine by which the creasing orfolding of the duck over the channel-lip is accomplished (Fig. 7).Bolted toa bracket 20 forming the extension of a reinforcing rib 1* onthe bed-plate is a U-shaped gage 21, one arm of which is securedadjustably to said bracket (a slot 8 being provided to permit of anadjustment to and from the blade 18), the upper inner corner of the gagecoming in contact with the toe end of the channel as the sheet D ispassed or pulled across the knives, thus measurably arresting themovement of the sheet and indicating the point at which the knife 18shall be brought down to cut off the sheet D.

The operation will now be readily understood from the foregoingdescription :It will be understood of course, that the upper face of thesheet of duck unwound from the roll D is coated with an adhesivecompound to which the shoe insole will well adhere as the sole is laidon the sheet. In practice, the operator pulls on the sheet and draws itover the bed-plate 2 and over the blocks 19, 19, toward the blade 18. Asthe sheet is passing over the blocks 19 the operator seizes an insole Eand deposits the same with the channel 6 down, on the gummed face of thesheet directly over the blocks 19, imparting a slight pressure to saidinsole so it may adhere to the sheet. The points or area of adhesionwill be limited more or less to the surfaces of the blocks and perhapsto points on either side thereof, but not sufficiently to cause thesheet to adhere to, or disturb the channel-lip e, for as previouslystated, the channel-lip must be intact and at right angles to the planeof the insole, when the latter is taken to the insole machine to havethe duck creased over the channel-lip. The blocks or ridges 19 thusserve to raise the center of the sheet D allowing the sides of thelatter to droop away from the channel-lip and thus avoid disturbing thelatter (Fig. 6). That is the function of the blocks. With the insolethus adhering to the sheet, the latter is drawn along until the toe ofthe channellip strikes or engages the corner of the member 21. Since thetoe of the channel-lip is quite close to the toe of the insole proper,and since the member 21 is removed from the blade 18 a distanceconsiderably in excess of the margin of the insole left projectingbeyond the channel-lip, it follows that when the blade 18' is broughtdown on the sheet D, it will sever the latter a slight distance beyondthe toe of the insole (Figs. 1, 2). For different lengths of insolesdifferent lengths of blocks 19 may be used, for which purpose asuflicient number of openings 0 are left in the bed 2 for the screws bywhich the blocks are held in place. So too, may the gage 21 be adjustedto vary the position of the point at which the sheet D is to be severed.A roll such as D usually accommodates about four hundred insoles more orless.

Having described my invention, what I claim is p 1. In combination witha bed for the passage of sheet material, a formation raised above thesurface of the bed and traversed by the medial portion of said sheetwhereby the medial portion of the sheet is raised and the sides areallowed to droop.

2. In combination with a bed for the passage of sheet material, a ridgeformation on the bed traversed by the medial port-ion of said sheetwhereby the medial portion of the sheet is raised and the sides areallowed to droop, and means at the discharge end of the bed for severingthe sheet into predetermined lengths.

3. In combination with a bed for the passage of sheet material, a ridgeformation on the bed traversed by the medial portion of said materialwhereby the medial portion of the sheet is raised and the sides areallowed to droop; the exposed face of the sheet be ing coated withadhesive for pasting the sheet to an insole provided with a marginalchannel-lip facing the sheet, a movable knife mounted across the path oftravel of the sheet, and a gage positioned beyond theknife and engagingthe toe end of the channel for momentarily arrest-ing the moving sheet,and means for actuating the knife and severing the sheet, thusmomentarily arrested.

4:. A machine of the character described comprising a bed-plate, a blockmounted over the bed over which a sheet of adhesive coated duck isadapted to be'passed, said sheet drooping from the block toward the bed,whereby upon the placing of a lipped insole on the sheet the lip will beundisturbed by the gummed face of the sheet, a stationary blade at oneend of the bed over which the sheet is passed, an oscillating bladecooperating with the stationary blade for severing the sheet, and a gagemounted at a point outside the blades and engaging the toe end of thelip of the insole for measurably arresting the movement of the sheet,and determining the point at which the same is to be severed.

5. In combination with a bed over which a sheet is to be passed, a ridgepositioned on the bed in the path of the medial portion of the sheet forraising the center of the sheet ofl" the bed and allowing the sides ofthe sheet to droop, for the purpose set forth.

6. In a machine of the class described, a

Copies of this patent may be obtained. for five cents each, byaddressing the bed, and means raised above the bed for engaging themedial portion of a sheet passed over the bed, and raising said medialportion off the bed the sides of the sheet drooping down from saidmedial portion, for the purpose set forth.

In testimony whereof I aflix my signature, in presence of two witnesses.
